Bacteria isn't all bad.

And so, the question for my lab is whether you want to think about all the good things that bacteria do, or all the bad things that bacteria do.

And these are all true, but you're like, look, you know, on balance, I still think bacteria is a bad thing.

Bacteria.

Pathogenic bacteria are bacteria that can cause infection.

The scale is bad here because if I were to scale it right, the bacteria would be about the size of this mitochondria.

Rotten, maggotinfested bacteria.

Hey look, this bacteria should, you know, I am some bacteria said

This is a bacteria.

Bacteria can cause depression.

I collaborate with bacteria.

Hey, these are bacteria.

We genetically engineer bacteria.

Attack Bacteria at once!

And this whole perception of bacteria being a bad thing is probably a good reason why almost any soap you see now will say antibacterial on it.

Really only two things, bacteria are going to be prokaryotic and the the archaea bacteria,

So this represent this would be just a few little bacteria here, many, many bacteria...

So this is the bacteria.

That's my bacteria right there.

You want to kill bacteria.

The esca holds bioluminescent bacteria.

The bacteria see the danger.

How does nature repel bacteria?

It's not like we're mostly bacteria by mass, although we are mostly bacteria by actual cells.

But since bacteria have hard walls, they will just inject the DNA inside of the bacteria.

So now that we found bacteria that could break down phthalates, we wondered what these bacteria were.

Some bacteria figured out how to stay away from penicillin, and it went around sort of creating its little DNA information with other bacteria, and now we have a lot of bacteria that are resistant to penicillin, because bacteria communicate.

Without water, the bacteria won't survive.

Bonnie Bassler on how bacteria talk

Bacteriology is the study of bacteria.

You say bacteria, those are germs.

I have a bacteria right here.

They attack bacteria, they kill them.

Let me say it's a bacteria.

We heard that bacteria eat oil?

In a petri dish, bacteria grow.

These bacteria live in a bottle.

Roughly 1 100 of a bacteria.

You cannot treat Bacteria this way.

Bad Pentagon, bad!

Xylitol cannot be fermented by these bacteria, so the bacteria have difficulty thriving, thus helping to prevent plaque formation.

And the bacteria, there was kind of this space around it, and the bacteria couldn't get close to it.

What was actually interesting to us was not that the bacteria made light, but when the bacteria made light.

Bad person. Bad person.

So bad! Really bad!
